A rotating shaft for turnably supporting the toilet lid and a rotating shaft for turnably supporting the toilet seat are separated, and the relative position of the toilet lid cushion to the toilet lid is changed according to a contact position between the toilet seat and the toilet lid cushion depending on an opening angle between the toilet lid and the toilet seat.

Description

  The present invention relates to a toilet seat device, and more particularly, to a toilet seat device including a toilet lid cushion disposed on the lower surface of a toilet lid.

  Generally, in a toilet seat device including a toilet seat and a toilet lid, a cushion made of an elastic body such as rubber is provided at a position where the toilet seat and the toilet lid come into contact with each other. When the toilet lid is closed by this cushion, the toilet lid and the toilet seat are prevented from colliding with each other and generating a loud sound. Moreover, when the toilet seat is opened by this cushion, the toilet lid and the toilet seat are prevented from directly colliding with each other to generate a loud sound (Patent Document 1).

  On the other hand, there has been proposed a toilet seat device in which a rotation shaft that supports the rotation of the toilet seat and a rotation shaft that supports the rotation of the toilet lid are not coaxial, but are separated from each other.

  The rotation shaft that supports the rotation of the toilet seat and the rotation shaft that supports the rotation of the toilet lid are separated from each other. The position in contact with the toilet seat is variable in the vertical direction of the rotation axis with respect to the toilet seat.

  At this time, since the position of the toilet lid cushion is fixed with respect to the toilet lid, sliding between the toilet lid and the toilet seat occurs with the opening and closing of the toilet lid and the toilet seat. In contrast, when the toilet seat and the toilet lid are in a closed state, in addition to the toilet lid cushion that contacts the toilet seat and prevents the toilet seat and the toilet lid from contacting each other, the toilet seat and the toilet lid that accompany the opening and closing of the toilet seat and the toilet lid A toilet seat device is proposed that includes a shock absorber that prevents a scratch caused by rubbing (Patent Document 2).

  This shock absorber enhances slidability and prevents the toilet seat and toilet lid from being scratched, but the contact sound between the toilet seat and the toilet lid when the toilet seat is opened is compared to the toilet lid cushion, which is a soft member Then there is a problem that it is inferior. Furthermore, since the shock absorber is not intended to prevent the toilet seat and the toilet lid from being rubbed together, depending on the state of use, the shock absorber or the toilet seat may be scratched due to the friction between the shock absorber and the toilet seat. It is difficult to prevent scratches completely.

  The present invention provides a toilet seat device that can reduce collision noise generated when the toilet seat and the toilet lid are opened and closed, and can prevent the toilet seat and the toilet lid from being scratched due to the opening and closing of the toilet seat and the toilet lid. The purpose is to do.

  According to a first aspect of the present invention, there is provided a main body portion installed on a toilet bowl, a toilet lid rotatably supported on the main body portion, a toilet seat rotatably supported on the main body portion, A toilet lid cushion provided on the back surface for preventing contact between the toilet seat and the toilet lid when the toilet seat and the toilet lid are opened and closed, and a rotating shaft that supports the rotation of the toilet lid and a rotation of the toilet seat The rotation axis that supports the movement is spaced apart from each other, and the relative position of the toilet lid cushion with respect to the toilet lid according to the contact position of the toilet seat and the toilet lid cushion according to the opening angle between the toilet lid and the toilet seat A toilet seat device having a variable position.

  According to this toilet seat device, since the position of the toilet lid cushion is variable, the contact position of the toilet lid cushion with the toilet seat can be made constant regardless of the open / closed state of the toilet seat and the toilet lid. Therefore, it is possible to reduce a collision sound generated when the toilet seat and the toilet lid are opened and closed, and to prevent the toilet seat and the toilet lid from being scratched due to the opening and closing of the toilet seat and the toilet lid.

  A second invention is the toilet seat device according to the first invention, wherein the toilet lid cushion is provided so as to be slidable in a vertical direction of a rotation shaft that supports the rotation of the toilet lid.

  According to this toilet seat device, since the toilet lid cushion slides in the vertical direction of the rotation axis of the toilet lid, when the toilet lid and the toilet seat are opened and closed while the toilet seat and the toilet lid cushion are in contact, the toilet seat and the toilet lid As the relative position changes, the toilet lid cushion slides in the vertical direction, and the relative position between the toilet seat and the toilet lid cushion does not change. Thereby, while being able to reduce the collision sound generated when opening and closing the toilet seat and the toilet lid, it is possible to prevent the toilet seat and the toilet lid from being scratched due to the opening and closing of the toilet seat and the toilet lid.

  A third invention is the toilet seat device according to the second invention, further comprising an elastic body for urging the toilet lid cushion in the vertical direction.

  According to this toilet seat device, when the toilet seat is not in contact with the toilet lid cushion, the toilet lid cushion can be arranged at substantially the center of the slide range. Thereby, the deviation of the position of the toilet lid cushion 110 when nothing is contacting the toilet lid cushion 110 can be eliminated.

The toilet seat device 20 includes a toilet lid 100, a toilet seat 200, a main body 300, and a toilet lid cushion 110 provided on a back surface (a surface facing the toilet seat 200 when the toilet lid 100 is closed) 100r. It is equipped with. The main body 300 of the toilet seat device 20 of the present embodiment is installed behind the toilet unit 400. In the present embodiment, the front direction of the user sitting on the toilet seat 200 in a normal use state is referred to as the front, and the back direction is referred to as the rear.

  The toilet apparatus 10 according to the present embodiment is a “tap water direct pressure type” having a tank for storing wash water, and a valve mechanism for controlling the wash water flowing to the toilet bowl is provided in the main body 300. However, the present invention is not limited to this specific example, and can be similarly applied to a so-called “low tank type” toilet apparatus.

  A toilet seat 200 and a toilet lid 100 are pivotally supported on the main body 300 so as to be freely opened and closed. As shown in FIG. 3, the toilet seat 200 is pivotally supported by a rotation shaft 320 provided relatively in front of the main body 300. On the other hand, the toilet lid 100 is pivotally supported by a rotating shaft 310 provided relatively behind the main body 300. That is, the rotation shaft 320 of the toilet seat 200 and the rotation shaft 320 of the toilet lid 100 are provided to be separated in the front-rear direction.

  In addition, an “electric opening / closing mechanism” that automatically opens and closes the toilet lid 100 and the toilet seat 200 may be incorporated in the main body 300. That is, when the presence of the user is detected by a sensor (not shown) or the like, the toilet lid 100 is automatically opened by the electric opening / closing mechanism, or when the presence of the user is not detected, the toilet seat 200 and the toilet lid 100 are automatically closed.

  The main body 300 may further be provided with a function as a “sanitary washing device”. That is, in response to a user's switch operation or the like, a water discharge nozzle (not shown) extends from the main body unit 300 into the bowl of the toilet unit 400 and injects hot water from a water discharge port provided near the tip thereof. It is possible to clean the user's “buttock” and the like. The main body 300 may further be appropriately provided with various mechanisms such as a “deodorizing unit”, a “warm air unit”, and an “indoor heating unit”. In this case, a seating sensor is provided on the front surface of the main body 300, and an exhaust hole of the “deodorizing unit”, a hot air discharge hole of the “indoor heating unit”, and the like are appropriately provided on the side surface.

Next, the toilet lid cushion will be described below with reference to FIGS. 4 and 5.
FIG. 4 is a schematic cross-sectional view showing the position of the toilet lid cushion in the opened / closed state of the toilet lid and toilet seat according to one embodiment of the present invention.
FIG. 4 shows a schematic cross-sectional view taken along line BB shown in FIG.
FIG. 5 is a partially enlarged view showing a toilet lid cushion according to one embodiment of the present invention.
FIG. 5 is a schematic cross-sectional view taken along line AA shown in FIG.

  First, Fig.4 (a) represents the toilet lid 100 and the toilet seat 200 in a fully open state. In this state, the tip of the toilet seat 200 is in contact with and protected near the center of the toilet lid cushion 110. That is, by providing the toilet lid cushion 110, it is possible to prevent damage caused by the tip of the toilet seat 200 coming into contact with the back surface 100r of the toilet lid 100.

  Further, when the toilet seat 200 is changed from the fully closed state to the fully opened state with the toilet lid 100 fully opened, the toilet seat 200 comes into contact with the toilet lid cushion 110. As a result, it is possible to prevent the toilet lid 100 and the toilet seat 200 from colliding directly and generating a loud sound.

  Further, the toilet lid cushion 110 supports the toilet seat 200 in a state in which the toilet lid cushion 110 is in contact with the distal end portion of the toilet seat 200. As a result, even when an external force or impact is applied to the toilet seat 200 in the opened state, the toilet lid cushion 110 absorbs this, and deformation and destruction of the toilet lid 100 and the toilet seat 200 can be suppressed.

  Thus, since the toilet lid cushion 110 abuts on the tip of the toilet seat 200 and supports the toilet seat 200 in a state where the toilet lid 100 is opened, the material is softer than the material of the toilet seat 200 and is opened. It is desirable to have elasticity or plasticity that can absorb an external force or an impact applied to the toilet lid 100 in a wet state. From these viewpoints, as the material of the toilet lid cushion 110, for example, a soft resin such as rubber or silicone, a foamed resin such as urethane, or the like can be used.

  FIG. 4B shows a state in which the toilet lid 100 and the toilet seat 200 are slightly closed from the fully opened position. Even in this state, the tip of the toilet seat 200 abuts and is protected near the center of the toilet lid cushion 110. That is, when the toilet lid 100 and the toilet seat 200 start to close from the position of FIG. 4A, the relative position of the toilet lid cushion 110 with respect to the toilet lid 100 is variable. As a result, the tip of the toilet seat 200 abuts in the vicinity of the center of the toilet lid cushion 110 even in the state of being slightly closed from the fully open position shown in FIG. 4B, as in the fully open state shown in FIG. Protected.

  FIG. 4C illustrates a state in which the toilet lid 100 and the toilet seat 200 are in the fully closed position. Even in this state, the tip of the toilet seat 200 abuts and is protected near the center of the toilet lid cushion 110. That is, the relative position of the toilet lid cushion 110 with respect to the toilet lid 100 is variable even if the toilet lid 100 and the toilet seat 200 start to close further from the position of FIG. As a result, even in the fully closed state shown in FIG. 4 (c), the toilet seat 200 is similar to the fully opened state shown in FIG. 4 (a) and slightly closed from the fully opened position shown in FIG. 4 (b). The tip is abutted and protected near the center of the toilet lid cushion 110.

  As can be seen from the series of operations shown in FIGS. 4A to 4C, the toilet seat 100 and the toilet lid cushion 110 are brought into contact with the toilet lid 100 according to the opening angle between the toilet lid 100 and the toilet seat 200. The relative position of the toilet lid cushion 110 is variable. That is, regardless of whether the toilet seat 200 and the toilet lid 100 are opened or closed, the tip of the toilet seat 200 is in contact with and protected in the vicinity of the center of the toilet lid cushion 110.

  Next, a structure in which the relative position of the toilet lid cushion 110 with respect to the toilet lid 100 is variable will be described with reference to FIG.

  As shown in FIG. 5, the toilet lid cushion 110 is held by the toilet lid 100 while being sandwiched between elastic bodies 150 a and 150 b provided on the toilet lid 100. That is, the toilet lid cushion 110 is provided so as to be slidable in the vertical direction p of the rotation shaft 310 (see FIG. 3) of the toilet lid 100. The toilet lid cushion 110 is urged toward the front end side (opposite to the rotating shaft 310) of the toilet lid 100 by one elastic body 150a, and the rear end side (of the rotating shaft 310 of the rotating shaft 310) is pressed by the other elastic body 150b. Side).

  The toilet lid 100 has, for example, a double structure in which a front surface member 100a and a back surface member 100b are combined. Ribs L1 and L2 are provided at regular intervals in the vertical direction p between the front surface member 100a and the back surface member 100b. Thereby, a predetermined space is provided between the front surface member 100a and the back surface member 100b.

  The back member 100b is provided with a long hole h extending in the vertical direction p, for example. The long hole h is provided between the rib L1 and the rib L2. Elastic bodies 150a and 150b are provided in the space S surrounded by the ribs L1 and L2, the front surface member 100a and the back surface member 100b.

  The toilet lid cushion 110 has a flat plate portion 110a and a convex portion 110b. The convex part 110b is provided in the approximate center of the flat plate part 110a. The flat plate portion 110a is larger than the long hole h and is disposed so as to cover the long hole h. On the other hand, the convex part 110b is smaller than the size of the long hole h. The convex portion 110b is provided on the long hole h side of the flat plate portion 110a, and is arranged from the long hole h toward the space S. That is, the toilet lid cushion 110 is attached so that the convex portion 110b is inserted into the long hole h and the flat hole 110a covers the long hole h.

  The width of the convex portion 110b is slightly narrower than the width of the long hole h. Thereby, the convex part 110b is guided to the length direction (vertical direction p) of the long hole h. Therefore, the toilet lid cushion 110 is slidable within the gap in the vertical direction p between the convex portion 110b and the long hole h. The size of the flat plate portion 110a is, for example, such a size that the long hole h cannot be seen even if the toilet lid cushion 110 slides to the maximum in the vertical direction p. Thereby, even if there is the long hole h, it is hidden by the toilet lid cushion 110, so that the appearance is not impaired.

  In the space S, one elastic body 150a is provided between the rib L1 and the convex portion 110b, and the other elastic body 150b is provided between the rib L2 and the convex portion 110b. Although the elastic bodies 150a and 150b shown in FIG. 5 are coil springs, the elastic bodies 150a and 150b are not limited to coil springs. For example, a torsion coil spring or a leaf spring may be used.

  By being urged by the elastic bodies 150a and 150b, the toilet lid cushion 110 is disposed at a substantially central position in the slide range. Thereby, the deviation of the position of the toilet lid cushion 110 when nothing is contacting the toilet lid cushion 110 can be eliminated.

Next, the operation of the toilet lid cushion 110 accompanying the opening / closing operation of the toilet lid 100 and the toilet seat 200 will be described.
First, in a state where the toilet seat 200 is not in contact with the toilet lid cushion 110, the toilet lid cushion 110 is disposed at a substantially central position in the slide range by the balance of the urging forces of the elastic bodies 150a and 150b. Each of the elastic bodies 150a and 150b can be expanded and contracted in the vertical direction p.

  Next, in the fully opened state shown in FIG. 4A, the tip of the toilet seat 200 abuts in the vicinity of the middle of the toilet lid cushion 110. When the toilet seat 200 and the toilet lid 100 are moved from the fully opened state shown in FIG. 4A to a state where the toilet seat 200 and the toilet lid 100 are slightly closed from the fully opened position shown in FIG. 4B, the distal end portion of the toilet seat 200 is in the middle of the toilet lid cushion 110. From the state of contact in the vicinity, an attempt is made to slide to the upper side of the toilet lid cushion 110 (the front end side of the toilet lid 100). However, as the relative position of the toilet seat 200 and the toilet lid 100 changes, one elastic body 150a contracts and the other elastic body 150b expands. Due to the expansion and contraction of the elastic bodies 150a and 150b, the toilet lid cushion 110 also changes the relative position with respect to the toilet lid 100 upward. As a result, the front end portion of the toilet seat 200 is kept in contact with the vicinity of the center of the toilet lid cushion 110.

  More specifically, the contraction force when one elastic body 150a contracts is the sliding resistance generated when the front end of the toilet seat 200 tries to slide on the upper side of the toilet lid cushion 110. It is set to be the same. Therefore, the elastic body 150a contracts due to the sliding resistance, so that the relative position of the toilet lid cushion 110 with respect to the toilet seat 200 changes, and as a result, the tip of the toilet seat 200 abuts near the center of the toilet lid cushion 110. State is maintained.

  When the toilet seat 200 and the toilet lid 100 move from the state shown in FIG. 4B to the fully closed state shown in FIG. 4C, the tip of the toilet seat 200 tries to slide further upward on the toilet lid cushion 110. To do. In this case, the elastic bodies 150a and 150b are further expanded and contracted, and the relative position of the toilet lid cushion 110 with respect to the toilet lid 100 is further changed upward. As a result, the front end portion of the toilet seat 200 is kept in contact with the vicinity of the center of the toilet lid cushion 110.

  When the toilet seat 200 and the toilet lid 100 are moved from the fully closed state shown in FIG. 4C to the fully opened state shown in FIGS. 4B and 4A, the operation described above is opposite. The toilet lid cushion 110 moves in the direction of. As a result, the front end portion of the toilet seat 200 is kept in contact with the vicinity of the center of the toilet lid cushion 110.

  Note that when only the toilet lid 100 or the toilet seat 200 is opened and closed while the distal end portion of the toilet seat 200 is in contact with the toilet lid cushion 110, the distal end portion of the toilet seat 200 is separated from the toilet lid cushion 110. In this case, the toilet lid cushion 110 is returned to a substantially central position in the slide range by the urging force of the elastic bodies 150a and 150b.

  When the toilet lid cushion 110 is at a position substantially in the center of the slide range, the distal end portion of the toilet seat 200 is the flat plate portion 100a of the toilet lid cushion 110 at any angle within the movable range of the toilet lid 100 and the toilet seat 200. Can abut. That is, no matter which position in the middle of opening / closing of the toilet lid 100 and the toilet seat 200, the front end of the toilet seat 200 and the toilet lid cushion 110 abut, when opening and closing the toilet lid 100 and the toilet seat 200 together, The relative position between the tip and the toilet lid cushion 110 is maintained.

  Thus, in the toilet seat apparatus 20 according to the present embodiment, the contact position between the toilet seat 200 and the toilet lid cushion 110 does not change. As a result, it is possible to prevent the toilet seat 200, the toilet lid 100, and the toilet lid cushion 110 from being scratched due to the opening and closing of the toilet seat 200 and the toilet lid 100.

  In the above description, the toilet lid cushion 110 is biased by the two elastic bodies 150a and 150b. However, the toilet lid cushion 110 may be biased by any one of the elastic bodies 150a and 150b.

  Further, the toilet lid cushion 110 may be moved by its own weight without being urged. In this case, as shown in FIG. 1, by opening only the toilet lid 100, the toilet lid cushion 110 moves to the lower side of the sliding range (the rear end side of the toilet lid 100) by its own weight. When the toilet seat 200 is opened in this state, the tip of the toilet seat 200 comes into contact with the toilet lid cushion 110. Then, the toilet lid 100 and the toilet seat 200 are both closed with the front end portion of the toilet seat 200 in contact with the toilet lid cushion 110, so that the relative position between the front end portion of the toilet seat 200 and the toilet lid cushion 110 is maintained. The lid cushion 110 slides, and the toilet lid 100 and the toilet seat 200 can be closed without changing the contact position between the toilet seat 200 and the toilet lid cushion 110.

  Alternatively, the toilet lid cushion 110 may be slid according to the opening / closing angle of the toilet lid 100 using a link mechanism, gears, wires, or the like. In this case, when the toilet lid 100 is fully opened, the toilet lid cushion 110 is moved to the lower side of the sliding range (the rear end side of the toilet lid 100), and when the toilet lid 100 is fully closed, the toilet lid cushion 110 is moved. What is necessary is just to make it move to the upper side (the front end side of the toilet lid 100) of a slide range. As a result, when the toilet lid 100 and the toilet seat 200 are opened and closed, even if the relative position of the toilet seat 200 to the toilet lid 100 changes, the toilet lid cushion 110 slides according to the angle of the toilet lid 100, and the toilet seat 200 and the toilet lid cushion The toilet lid 100 and the toilet seat 200 can be opened and closed without changing the contact position with 110.

  As described above, even when the elastic bodies 150a and 150b are not urged, the toilet lid cushion 110 slides, so that the toilet seat 200, the toilet lid 100, and further the stool are opened and closed with the opening and closing of the toilet seat 200 and the toilet lid 100. Abrasion of the lid cushion 110 can be prevented.

  The embodiment of the present invention has been described above. However, the present invention is not limited by these descriptions. As long as the features of the present invention are provided, those skilled in the art appropriately modified the design of the above-described embodiments are also included in the scope of the present invention.
